UNITED STATES CIVIPANY, @FERTE/OIT, IWIGI'IIGAN, A CORFORATIN Ofl NCHEGAN.

I) O ORCHECK.

Application led. April 29, 1922.

To mtl, 'ui/loin it' may cou-ocra:

lie it lrnouf'n that I, PAUL RissMAN, a citi zen oi" the United States oit Ajlnerica, residing at Detroit, in the county of lVayne and State of Michigan, have invented certain new and useiul Improvements in Doorchecls, ot which the following is a. specifica.- tion, reference heilig had therein to the accon'ipanying drawings.

The invention relates to door checks such as are used ttor limiting the opening of doors oit automobiles and for similar purposes, and the invention consists in. the novel construc tion as hereinafter set torth.

In the drawings :m

li`ignre l is a horizontal section. through a. portion ot an automobile body and door showing my in'qnoved check applied thereto, the door being in closed position;

Figure 2 is a siniilar view in the open position ot the door;

Figure 3 is a perspective View of the check detached.

Figure 4 is a longitudinal section showing the connection through the end portion ot the check;

ln the present state of the art it is usual to torin door checks, 'tor the purpose above described, et straps oi leather or similar inaterial rigidly attached at one end to the door and at the other end to the door casing or ilranie. When the doei' is swung open against the check, the inertia is suiiicient to throw aconsiderable stress upon the strap. This frequently results in either breaking the strap er tea-ring it frein its attachment. My improved construction is one that can be niore cheaply manufactured than the usual consti'uctions and also has the advantage that the shock upon the check is cushioned, thereby .lessening the danger et injuries.

In detail, A is a short section et wire cable or other nonfstretchable resiliently flexible material. This cable is preferably covered with a braid or fabric covering F. C and C are anchor plates, liu'eferably ot pressed sheet metal, which, as shown, are in the iorin ot circular disks centrally apertured for the passage of the cable therethrough and hav ing a series ol' countersunk apertures D tor engaging the heads oi the securing screws E. Surrounding the central aperture in each disk is a fla-nge F which 'forms a bearing for the cable. At one end of the cable the plate C is rigidly attached, preferably by Serial N0. 557,295.

inserting a screw G, which spreads the strands of the cable and securelv clamps the saine against the tlange F. This clamping is rendered. more secure by iiaring the flange AFfas shown, so that the insertion or the `tapering screw will produce a wedging eil'ect. The other anchor plate C is loosely slidable upon the cable and a yielding abut nient is termed tor this plate by a spring H sleeved upon the cable and a haring collar I, which is secured to the end et the cable by a screw J in a similar manner to the securing of the anchor plate C.

Viith the construction as described, in applying the saine to a door, one ot the plates such as C is secured to the door ,traine post K, while the other plate C' is secured to the post L ol? the door. The ioriner post is bored at M for the passage ol the projecting portion et the cable, together with a spring H and collar I. Thus, when the door is closed, the plates C and C will be in proximity and the cable, spring and collar will extend through the bore M. On the other hand, when. the door is swung open, the cable will be drawn through the plate C until the spring H abuts against the flange F. rlhe further nioveinent ci the door will. conipress the spring and will cushion the shocl.

rlhe construction described can be nranufactured at sinall cost and will have a long life, inasmuch as the flexing of the cable within the elastic liniitl oi the material. lt is also a simple operation to attach the check to a door.

that l cla-ini as iny invention is:

l. A door check comprising anchor plates oppositely secured to the posts oi. the door and door frame, a non-stretchable stranded cable passing through apertures in said plates and through an aligned aperture in one of said posts, a terrule or collar sur rounding each end portion ot the cable, and a wedge inserted centrally in the end of the cable 'tor clamping the saine to said collar or iferrule.

2. A door check comprising anchor plates secured respectively to the poets et the door and door traine, a stranded cable passing through central apertures in said plates and through an aligned aperture in one el' said posts, collars or errules surrounding the opposite ends of the cable, one of said collars being integral with one of said plates, and a member inserted in the end et. the

lll)

cable for wedging the strands thereof against said eollar or -fel-rule to seenrely elainp the saine.

3. A door cheek comprising anchor plates oppositely secured to the posts of the door and door traine, a resilient stranded Cable extending through apertures in said plates and an aligned aperture in one of said posts, Collars or ferrules surrounding the ends of said eable, and screws inserted into the ends of the cable to spread the strands thereof and to 'wedge the saine into clamping engagement with said collars or barrels.

4. A door eheok comprising anchor plates said eahle, one of said eollars being integral with one of said plates, serews for engaging the ends of said cables to `wedge the strands thereof into elalnping engagement with said collars or fer-rules, and :L spring sleeved on said cable intermediate one oit said collars or ferrules and the adjacent anchor plate.

5. A door eheek Comprising anchor plates seeured respeetivelusY to the posts of' the door and door traine, a cable passing through apertures in said plates and through an aperture in one of said posts, eollars sin rounding the opposite end ot the Cable, one of said Collars being integral with. one ot said plates, and means l.tor securing the ends of the eable to said collars.

In testimony whereof I aiix my signature.
